BACKGROUND OF THE INVENTION

Cancer is a leading cause of death throughout the world. A limitation of prevailing therapeutic approaches, e.g. chemotherapy and immunotherapy is that their cytotoxic effects are not restricted to cancer cells and adverse side effects can occur within normal tissues. Consequently, novel strategies are needed to better target cancer cells.

Synthetic lethality arises when a combination of deficiencies in the expression of two or more genes leads to cell death, whereas a deficiency in only one of these genes does not. The concept of synthetic lethality originates from studies in drosophila model systems in which a combination of mutations in two or more separate genes leads to cell death (in contrast to viability, which occurs when only one of the genes is mutated or deleted). More recently, a multitude of studies have explored maladaptive genetic changes in cancer cells that render them vulnerable to synthetic-lethality approaches. These tumor-specific genetic defects lead to the use of targeted agents that induce the death of tumor cells while sparing normal cells.

Methionine adenosyltransferase 2A (MAT2A) is an enzyme that utilizes methionine (Met) and adenosine triphosphate (ATP) to generate s-adenosyl methionine (SAM). SAM is a primary methyl donor in cells used to methylate several substrates including DNA, RNA and proteins. One methylase that utilizes SAM as a methyl donor, is protein arginine N-methyltransferase 5 (PRMT5). While SAM is required for PRMT5 activity, PRMT5 is competitively inhibited by 5′methylthioadenosine (MTA). Since MTA is part of the methionine salvage pathway, cellular MTA levels stay low in a process initiated by methylthioadenosine phosphorylase (MTAP).

MTAP is in a locus on chromosome 9 that is often deleted in cells of patients with cancers from several tissues of origin including central nervous system, pancreas, esophageal, bladder and lung (cBioPortal database). Loss of MTAP results in the accumulation of MTA making MTAP-deleted cells more dependent on SAM production, and thus MAT2A activity, compared to cells that express MTAP. In an shRNA cell-line screen across approximately 400 cancer cell lines, MAT2A knockdown resulted in the loss of viability in a larger percentage of MTAP-deleted cells compare to MTAP WT cells (see McDonald et. al. 2017 Cell 170, 577-592). Furthermore, inducible knockdown of MAT2A protein decreased tumor growth in vivo (see Marjon et. al., 2016 Cell Reports 15(3), 574-587). These results indicate that MAT2A inhibitors may provide a novel therapy for cancer patients including those with MTAP-deleted tumors.

(2014), the disclosure of which is incorporated herein by reference in its entirety. The protected derivatives of compounds of the present disclosure can be prepared by methods well known in the art.

The present disclosure also includes prodrugs of the compound of Formula (I) (IA), (II), (IIA) and (IVA) and (IV), or a pharmaceutically acceptable salt thereof. Prodrugs of the compounds described herein are those compounds that readily undergo chemical changes under physiological conditions to provide the compounds of the present invention. An example, without limitation, of a prodrug would be a compound which is administered as an ester (the “prodrug”), but then is metabolically hydrolyzed to the carboxylic acid, the active entity. Additionally, prodrugs can be converted to the compounds of the present invention by chemical or biochemical methods in an ex vivo environment. For example, prodrugs can be slowly converted to the compounds of the present invention when placed in a transdermal patch reservoir with a suitable enzyme or chemical reagent.

Certain compounds of Formulae (I) (IA), (II), (IIA) and (IVA) and (IV) can exist in unsolvated forms as well as solvated forms, including hydrated forms.

Methylthioadenosine phosphorylase (MTAP) is an enzyme found in all normal tissues that catalyzes the conversion of methylthioadenosine (MTA) into adenine and 5-methylthio-ribose-1-phosphate. The adenine is salvaged to generate adenosine monophosphate, and the 5-methylthioribose-1-phosphate is converted to methionine and formate. Because of this salvage pathway, MTA can serve as an alternative purine source when de novo purine synthesis is blocked, e.g., with antimetabolites, such as L-alanosine.

Many human and murine malignant cells lack MTAP activity. MTAP deficiency is not only found in tissue culture cells but the deficiency is also present in primary leukemias, gliomas, melanomas, pancreatic cancers, non-small cell lung cancers (NSLC), bladder cancers, astrocytomas, osteosarcomas, head and neck cancers, myxoid chondrosarcomas, ovarian cancers, endometrial cancers, breast cancers, soft tissue sarcomas, non-Hodgkin lymphomas, and mesotheliomas. It has been reported by K. Marjon et al, Cell Reports 15 (2016) 574-587, incorporated herein by reference, that proliferation of cancer cells that are MTAP null is inhibited by knocking down MAT2A expression with shRNA. An MTAP null cancer is a cancer in which the MTAP gene has been deleted or lost or otherwise deactivated or a cancer in which the MTAP protein has a reduced or impaired function.

Accordingly, in an embodiment of the present disclosure there is provided a method for treating an MTAP null cancer in a patient wherein said cancer is characterized by a reduction or absence of MTAP expression or absence of the MTAP gene or reduced function of MTAP protein as compared to cancers where the MTAP gene is present and fully functioning, said method comprising administering to the patient in need thereof a therapeutically effective amount of a compound of Formula (I), (IA), (IA′), (II), (IIA), (IA′), or a subembodiment described herein or a pharmaceutically acceptable salt thereof.

The present disclosure also contemplates the use of the compounds of Formula (I), (IA), (IA′), (II), (IIA), (IIA′), or a subembodiment described herein, or a salt thereof in combination with immune checkpoint inhibitors. The tremendous number of genetic and epigenetic alterations that are characteristic of all cancers provides a diverse set of antigens that the immune system can use to distinguish tumor cells from their normal counterparts. In the case of T cells, the ultimate amplitude (e.g., levels of cytokine production or proliferation) and quality (e.g., the type of immune response generated, such as the pattern of cytokine production) of the response, which is initiated through antigen recognition by the T-cell receptor (TCR), is regulated by a balance between co-stimulatory and inhibitory signals (immune checkpoints). Under normal physiological conditions, immune checkpoints are crucial for the prevention of autoimmunity (i.e., the maintenance of self-tolerance) and also for the protection of tissues from damage when the immune system is responding to pathogenic infection. The expression of immune checkpoint proteins can be dysregulated by tumors as an important immune resistance mechanism. Examples of immune checkpoint inhibitors include but are not limited to CTLA-4, PD-1, PD-L1, BTLA, TIM3, LAG3, OX40, 41BB, VISTA, CD96, TGFβ, CD73, CD39, A2AR, A2BR, IDO1, TDO2, Arginase, B7-H3, B7-H4. Cell-based modulators of anti-cancer immunity are also contemplated. Examples of such modulators include but are not limited to chimeric antigen receptor T-cells, tumor infiltrating T-cells and dendritic-cells.

The present disclosure contemplates the use of compounds of Formula (I), (IA), (IA′), (II), (IIA), (IIA′), or a subembodiment described herein, or a salt thereof in combination with inhibitors of the aforementioned immune-checkpoint receptors and ligands, for example ipilimumab, abatacept, nivolumab, pembrolizumab, atezolizumab, nivolumab, and durvalumab.

Additional treatment modalities that may be used in combination with a compound of Formula (I), (IA), (IA′), (II), (IIA), (IIA′), or a subembodiment described herein, or a salt thereof include radiotherapy, a monoclonal antibody against a tumor antigen, a complex of a monoclonal antibody and toxin, a T-cell adjuvant, bone marrow transplant, or antigen presenting cells (e.g., dendritic cell therapy).

The present disclosure contemplates the use of compounds of Formula (I), (IA), (IA′), (II), (IIA), (IIA′), or a subembodiment described herein, or a salt thereof for the treatment of glioblastoma either alone or in combination with radiation and/or temozolomide (TMZ), avastin or lomustine.

The present disclosure encompasses pharmaceutically acceptable salts, acids or derivatives of any of the above.

Dosing

The compounds of Formula (I), (IA), (IA′), (II), (IIA), (IIA′), or a subembodiment described herein, or a salt thereof may be administered to a subject in an amount that is dependent upon, for example, the goal of administration (e.g., the degree of resolution desired); the age, weight, sex, and health and physical condition of the subject to which the formulation is being administered; the route of administration; and the nature of the disease, disorder, condition or symptom thereof. The dosing regimen may also take into consideration the existence, nature, and extent of any adverse effects associated with the agent(s) being administered. Effective dosage amounts and dosage regimens can readily be determined from, for example, safety and dose-escalation trials, in vivo studies (e.g., animal models), and other methods known to the skilled artisan.

In general, dosing parameters dictate that the dosage amount be less than an amount that could be irreversibly toxic to the subject (the maximum tolerated dose (MTD)) and not less than an amount required to produce a measurable effect on the subject. Such amounts are determined by, for example, the pharmacokinetic and pharmacodynamic parameters associated with ADME, taking into consideration the route of administration and other factors.

An effective dose (ED) is the dose or amount of an agent that produces a therapeutic response or desired effect in some fraction of the subjects taking it. The “median effective dose” or ED₅₀ of an agent is the dose or amount of an agent that produces a therapeutic response or desired effect in 50% of the population to which it is administered. Although the ED₅₀ is commonly used as a measure of reasonable expectance of an agent's effect, it is not necessarily the dose that a clinician might deem appropriate taking into consideration all relevant factors. Thus, in some situations the effective amount is more than the calculated ED₅₀, in other situations the effective amount is less than the calculated ED₅₀, and in still other situations the effective amount is the same as the calculated ED₅₀.

In addition, an effective dose of a compound of Formula (I), (IA), (IA′), (II), (IIA), (IIA′), or a subembodiment described herein, or a salt thereof may be an amount that, when administered in one or more doses to a subject, produces a desired result relative to a healthy subject. For example, for a subject experiencing a particular disorder, an effective dose may be one that improves a diagnostic parameter, measure, marker and the like of that disorder by at least about 5%, at least about 10%, at least about 20%, at least about 25%, at least about 30%, at least about 40%, at least about 50%, at least about 60%, at least about 70%, at least about 80%, at least about 90%, more than 90%, where 100% is defined as the diagnostic parameter, measure, marker and the like exhibited by a normal subject.

In certain embodiments, the compounds of (I), (IA), (IA′), (II), (IIA), (IIA′), or a subembodiment described herein, or a salt thereof may be administered (e.g., orally) at dosage levels of about 0.01 mg/kg to about 50 mg/kg, or about 1 mg/kg to about 25 mg/kg, of subject body weight per day, one or more times a day, to obtain the desired therapeutic effect.

For administration of an oral agent, the compositions can be provided in the form of tablets, capsules and the like containing from 1.0 to 1000 milligrams of the active ingredient, particularly 1.0, 3.0, 5.0, 10.0, 15.0, 20.0, 25.0, 50.0, 75.0, 100.0, 150.0, 200.0, 250.0, 300.0, 400.0, 500.0, 600.0, 750.0, 800.0, 900.0, and 1000.0 milligrams of the active ingredient.

In certain embodiments, the dosage of the compound of Formula (I), (IA), (IA′), (II), (IIA), (IIA′), or a subembodiment described herein, or a salt thereof is contained in a “unit dosage form”. The phrase “unit dosage form” refers to physically discrete units, each unit containing a predetermined amount of the compound of Formula (I), (IA), (IA′), (II), (IIA), (IIA′), or a subembodiment described herein, or a salt thereof, either alone or in combination with one or more additional agents, sufficient to produce the desired effect. It will be appreciated that the parameters of a unit dosage form will depend on the particular agent and the effect to be achieved.
